In March 2014, 5 Australian airplanes were carring out a search operation over an area of 23,000 square kilometer in the Indian Ocean, 230 mil southwest of Perth, Australia. The track of the possible debris from the missing plane is described as the best track they have so far in this mysterious story.

Johan Nilsson is professor at the Department of Meteorology at Stockholm University and do research in oceanography. He says; the area that are now being scanned is called "The roaring forties", and is home to one of the world's strongest ocean currents in terms of volume of water transported. It's called the circumpolar ocean current, and makes the area, to say the least, a problematic place to search.

- These ocean currents are usually driven eastward. If we consider the highest speeds that can occur in this area, objects may drift a half meter per second in one day. In one hour, it means that it gets two kilometers. So, on one day it can travel around 50 kilometers, says Johan Nilsson.
